Two PHP functions performing basic Mingle operations

I share the code of two PHP functions performing basic Mingle operations (creating a card and updating a card) hoping it will help you to save some time. They can easily be adapted to perform other basic operations such that getting a card data or removing a card.

Code Snippet

// Mingle card creation function returning the Mingle number of the new card (use CURL library) 
function create_card($url, $parameters) 
{ 
$ch = curl_init(); 
if ($ch) 
{ 
// HTTP POST call configuration 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_HTTPHEADER, Array("Content-Type: application/x-www-form-urlencoded")); 
curl_setopt($ch, CURLOPT_POST, true); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $parameters); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_HEADER, true); 
// HTTP POST call 
$header = curl_exec($ch); 
curl_close($ch); 
// Card number extract from header data 
$pos1 = strpos($header, "/cards/") + 7; 
$pos2 = strpos($header, ".xml"); 
$number = substr($header, $pos1, $pos2 - $pos1); 
return $number;     
} else 
{ 
return ""; 
} 
} 
// Mingle card update function (use CURL library) 
function update_card($url, $parameters) 
{ 
$ch = curl_init(); 
if ($ch) 
{ 
// Creation of the file to send through the HTTP PUT call 
$putFile = tmpfile(); 
fwrite($putFile, $parameters); 
fseek($putFile, 0); 
// HTTP PUT call configuration 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_HTTPHEADER, Array("Content-Type: application/x-www-form-urlencoded")); 
curl_setopt($ch, CURLOPT_PUT, true); 
curl_setopt($ch, CURLOPT_INFILE, $putFile); 
curl_setopt($ch, CURLOPT_INFILESIZE, strlen($parameters)); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_HEADER, false); 
// HTTP PUT call 
curl_exec($ch); 
fclose($putFile); 
curl_close($ch); 
return true;     
} else 
{ 
return false; 
} 
} 
// Call examples
$card_number = create_card( 
"http://user:password@your.mingle.server:8080/api/v2/projects/my_project/cards.xml", 
"card[name]=A new story card&card[card_type_name]=Story");  
update_card( 
"http://user:password@your.mingle.server:8080/api/v2/projects/my_project/cards/123.xml", 
"card[name]=A new story card name&card[description]=A new description"); 
?>
